To a, whom, it rmty concern:

' Be it known that I, JULIUS J. CZEPULL, a of coal mined. subject of the Emperor of Germany, residing at Lancaster,Pennsylvania, have invented pounds of starch and reduce this in Warm certain new and useful Improvements in Arwater to a paste. To this I add three tificial Fuel, of which the following is a specipounds of glue which has been previously cation. issolved in about five quarts of water nd It is the object of my invention to provide boil the two together. To this mixture I an effective binder for use in the making of slowly mix five pounds of slaked lime and briquets from anthracite coal-dust, comboil the whole together. I-then add to the monly called cuhn or slush, but constituting the fine carbon particles which up to the present time is absolute waste, and has Many attempts have been made to secure a binder for this mate rial, but so far as I am aware no binder'has been produced which has been found to be sufiicientl y cheap in purpose, or which would with tand exposure to the elements without disintegration, or which would withstand 'the effect of combustion without falling to mixture one I stir this thoroughly with the whole. quantity of the bi nder is sufiicient to make up a ton of the culm or waste coal-dust, and mix the binder with the coal-dust very thoroughly and then press the resultant mixture into the form of briquet in a suitable press. I prefer to let the briquets stand for from twenty-four to forty-eight hours, so that they become thoroughly set, though they may be used at once.

What I claim 1s 1. A binder for coal-dust consisting of starch, glue, slaked lime and linseed -oil mixed thoroughly together in the presence of heat and afterward incorporated with the It is the aim of my invention to produce a binder which shall, first, be economical and which will enable me to 'manufacture briproduct at a cost which much cheaper than the expense of mining the coal; secondly, the' binder I have produced is not affected by Water and may therefore be exposed to the elements without detriment or any danger of disintegration, and, finally, the briquet made of the particles of coal-dust secured together by my binder will burn without falling apart and until every particle of the briquet has been consumed. The importance of an purpose described in view of the fact that millions of tons of this waste coal-dust 1s now to be found in the coal regions, and
